"Are you purple or blue?"
Silence from behind the shower curtain.
"Bec, purple or blue?" I said with a hint of urgency.
"I'm the one on the right. I've been using whatever one is on the right."
"Right is not a color."
Purple is on the right. I am feeling more and more sure that I was purple when this whole thing started. I remember thinking, "Becca's color as a baby was purple. It's my turn to be purple."
Finally, poking her head out of the shower, she said, "I think I was the blue toothbrush. But now, I'm on the right. The right is purple. I think that means we've switched."
